While wiping on a hardmode boss is annoying enough the double loading screens is very long time spent waiting. I have a fairly decent computer and using a new SSD to load the game from and still it takes time.
Why not just make the spawn point after defeat in instance just inside the door instead of just outside the door.
Also for convience please put a repair droid at entrance, like at the speeders in Enternity Vault. Having to walk around the entire ship to reach one is a bit much.
